Where is Mercury’s largest impact basin located?
Quick Answer
Mercury’s largest impact basin, Caloris Planitia, is on the planet’s eastern hemisphere. It is about 1,550 km across.
The Full Story
Caloris Planitia lies on Mercury’s eastern side and is one of the largest impact basins in the Solar System. It formed after a colossal asteroid or comet impact early in the planet’s history. The basin’s floor is surrounded by concentric rings and a rugged rim, and the impact also created disrupted terrain on the opposite side of Mercury. NASA’s MESSENGER mission provided much of the modern detail about its geology.
